This invention relates to boiler cleaning apparatus.

The invention will be fully and comprehensively understood from aconsideration of the following 5 detailed description when read inconnection with the accompanying drawing which form part of theapplication, with the understanding, however, that the improvementis'capable of extended application and is not confined to the exactshowing of the drawing nor to the precise construction described and,therefore, such changes and modifications may be made therein as do notaffect the spirit of the invention nor exceed the scope thereof asexpressed in the appended claim.

The drawing shows in front elevation the boiler having the usualequipment for blowing air into the boiler and also shows the apparatusof my invention connectedwith the usual air blowing apparatus. V

The numeral 5 indicates a boiler,,into the lower part of which, belowthe grate, air is blown by a blower '7 thru a pipe 8. A receptacle 9 forreceiving material cleaned from the boiler tubes is connected by meansof a pipe 10 to the pipe 8. A 25 valve 12 is positioned inthe pipe 8between its point of connection with the pipe 10 and'the' boiler. Avalve 15 is provided in the pipe 10. The latter pipe has an openingshown as closed by cap 17. The air inlet side of the blower 7 is coveredwith a screen 18 and on this screen is placed a semi-circular member 20,which carries a pipe 21 to which is connected! a flexible hose 23 theother end of said hose being connected to'a pipe 24 which has arubbercup 25 attached to its freeend. 2

When the tubes of the boiler are to be cleaned, the valves 12 and 15 areclosed and opened respectively andthe cup 25 is placed against the endof the tube or a series of tubes to be cleaned. The material removedfrom the tubes then passes thru the ,pipe 24 of the flexible hose 23and. the

pipe 21, thru the blower part of the pipe 8 into the pipe 10 and theninto the receptacle 9. When it is desired to force air thru the tubes ofthe boiler or to clean other parts of the boiler, the cap 17 is takenoff the pipe 10- and the hose 23 is fitted over the opening normallyclosed by the cap while the valves 12 and 15 are closed. The blower thenblows air through part of the pipe 8 and part of the pipe 10 and forcesit into the hose '23 and the pipe 24, the cup 25 being placed at a pointwhere it is desired to have the air pressure.

What is claimed is: a The combination with a tube boiler and itssetting, of a bloweiga pipe connecting said blower with the lower partof the boiler setting for conducting air under pressure from the blowerto the CHARLES BACHER.
